heat enters the atmosphere than escapes become some of it is absorbed and some of it is reflected
back by the blanket of heat-trapping gases. Heat melts ice, revealing tundra, which creates even
more effective heat-trapping gases are produced and released into the atmosphere. Water reflects
less heat than ice does because it is darker, which essentially speeds up global warming.
The average surface temperature given in the world fluctuates from year to year, but the trend is
certainly upwards, at least from 1960 and on. After 1960s, there is a much more significant upward
trend in the amount of CO2 (heat trapping gas) in parts per million by volume. So what? This leads
to more flooding, poor air quality, more frequent storms, and erosion of land. This essentially leads
to more deaths of people through not just storms, but also inability to cultivate land to grow food.
Looking at NASA calculations, we find that the Global Warming effects began in the northern
hemisphere, before they started spreading to the world. This climate change has resulted in a
decrease in the sizes of polar ice caps, and consequently increased sea levels. Nevertheless, global
warming is not only increasing the risk of flooding in the world, it is also leading to ocean
acidification due to the high levels of CO2 in the atmosphere.
Genetic Pollution: There has also been an increase in Genetic pollution. Genetic pollution refers to
the health and ecological dangers that may result from artificially splicing genes together.
Recombinant DNA is a technique that involves artificially joining bits of DNA from a donor to the
DNA of a host. This has been done in the past, where people have combined the DNA of fireflies
and tobacco plants, such that the final result has been glowing plants at night. This is however
ancient history! There is much more research being done, which can allow for amazing new
innovations. There is a possibility of being capable of eliminating all genes, which cause disease in
humans, or even helping in agriculture, mining, etc. Nevertheless, it should not be forgotten that
there are risks that are also resulting through this DNA modification. For example, there is more
and more use of DNA modification in agricultural facilities. They are producing products that are
more resistant to bugs, temperature, etc. However, there is a simple evolutionary fact that works
against this DNA modification. Bugs, and pests (weeds) that are more capable of attacking and
affecting the modified plants, will grow in numbers as other more conventional bugs would decline
in number. This would lead to a greater concentration of pests that are now immune to the
modified product, and if these bugs spread diseases, they would probably spread diseases that are
hardier and immune to conventional medication drugs.
Differentiating between an issue and a problem, an issue tends to be something that needs to be
fixed. A problem, or more specifically, a social problem, is what the world claims to be an issue and
shows concern in reducing the scope of this issue. Environmental issues become social problems
when three main conditions are met. First, policy-oriented scientists, the environmental movement,
